HARRow.

SPECIFICATION forming part of Letters Patent No. 251,418, dated December 27, 1881.

Application filed June 11,1881.

To all whom it may concern:

Be it known that I, MICHAEL DALEY, a citizen of the United States, resident of VVaterman, in the county of De Kalb and State of Illinois, have invented a new and valuable Improvement in Harrows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of my invention,'and Fig. 2 is a plan view.

This invention has relation to barrows; and it consists, mainly, in the construction and novel arrangement of devices, whereby the angular position of the teeth may be changed While the team is in motion; also,in the springcoupling for the draft, all as hereinafter more fully set forth, and particularly pointed outin the claim appended.

In the annexed drawings, the letters A A designate the transverse harrow-heams, which carry the teeth B.

0 O designate flexible rods or bars, having holes or loops a, which are made in the rods or bars by bending the latter, and to which the harrow-beams are hinged by means of staples b. This connection of the beams with the rods permits of a side rocking or end movement of the former, allowing for any transverse irregularity of the surface over which theharrow is drawn. These connecting-rods are placed under the beams, near the ends of the latter, at the sides of the harrow, and serve for the attachment for the draft. The beams are connected by a similar rod or bar, 0, above, and an oblique brace, D, should be'used to preserve the relative position of the beams, as indicated in the drawings. The arrangementofthe three bars, 0 O O, thoroughly braces the harrowframe, and yet permits a free movement.

E represents the draft-beam, having eyebolts 0 or perforated lugs, to which the spring- These couplings consist of elongated bent rods having transverse outwardly turned ends (I, which are sprung into engagement with the staples,lugs, or eyebolts of thedraft-beam. These couplings,

(N0 model.)

being attached by their ends to the draft-beam, act as braces, preventing side-thrust of the barrow-frame, while permitting a free rocking motion.

G indicates an uprightarm or lever, which is attached to one of the barrow-beams, and provided at or near its upper end with a loop or guide, 6, through which passes the stay-rod H, the forward end of" which is hinged to the front barrow-beam at g. The stay-rod is provided with a series ofnotches or holes, 71, for engagement with the end of the lever-lock K, which is pivoted to thearm G, and extendsto the rear in the form of a handle, 70, this handle portion being usually sufficientlywei ghted to insure the engagement of thelever-lock with the stayrod after the adjustment of the latter with reference to the beam lever or arm G. The leverlock K also serves to manipulate the beam-lever G, to which it is pivoted, so that the adjustment of said beam-lever and the entire set of barrow-beams can be effected to change the angle of the harrow-teeth while the team isin motion. In this mannner the operator is enabled at any time to reverse the inclination of the teeth to clear them from rubbish, or to set them at any angle required in pulverizing by the condition of the soil.

I am aware that harrows have been constructed with flexible bars, also with rods and links connecting the transverse beams, and do not claim such broadly.

Having described this invention, what I claim, and desire to secure by Letters Patent, is-

In a harrow, the combination of the flexible rods C, having loops a, hinged t0 the under side of the barrow-frame, the flexible rod C, connected to the top or face of the transverse beams by loops, and the oblique brace D, all arranged as described, to allow a limited flexible movement of the harrow-frame, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

MICHAEL DALEY.
